Frequently Asked Questions
Do I need consent for transactional SMS?
Although opt-in consent isn’t needed for transactional email, to send messages to a recipient’s phone number, you must have first received consent to do so.
As well as complying with the Telephone Consumer Protection Act (TCPA), receiving clear, informed opt-in consent from recipients will also ensure higher levels of engagement and lower opt-out rates.
How do I receive SMS replies?
With MailerSend's inbound routing feature, you can create inbound routes to have MailerSend receive incoming messages on your behalf and integrate them into your app.
What types of SMS can I send?
You can send any type of message in relation to your business as long as you have received opt-in consent and follow the Telephone Consumer Protection Act guidelines.
This includes, but is not limited to, shipping notifications, delivery updates, 2-factor authentication, appointment and event reminders, emergency alerts, one-time passwords, order status updates, booking/reservation confirmation and cancellation, payment and billing alerts, and general alerts, notices and updates.
